Divided andthis application July 1, 1948, Serial No. 36,334

7 Claims. (Cl. 346-133) This application is a division of our copendingapplication, Serial No. 563,918, filed November lates to recordingapparatus in the form of a time recorder of the type assigned toindividual workmen and used to record the time spent on a particular joband the cost of the labor and overhead to be assigned thereto. Timerecorders of this type are commonly referred to as job cost recorders orbench recorders.

Whereas in our parent application above referred to the principal objectthereof was to provide an improved form of time recorder which functionsto accumulate desired numerical data at a given time rate and whichoperates to record the totals of such data by applying data-representingmarks of electrically conducting material on a suitable record sheet,such as a standard record card commonly employed in connection withelectric accounting machines, the principal object of this invention isto provide a means for effectively marking the cards at the selectedindex point positions thereof with the conducting material in such amanner that it will be insured that all the interstices of the cardwhere the mark is to be positioned will be adequately filled with theconducting material, thus providing av mark which is positive in itselectrical conducting function when used for sensing purposes in anelectrical accounting machine.

Heretofore, in the absence of a mechanical means for applying conductingmarks to the surface of record cards designed for accounting machinepurposes, it has beencustomary to place these marks at selected indexpoint positions manually by means of a marking pencil, the crayonportion of which contains a conducting material. It has been found thatnot only does it require considerable skill for an operator to preparethe record cards rapidly and efficiently with a fair degree ofuniformity of the marks on the index point positions, but additionallyit requires extreme care for the operator to produce marks on the cardwhich are of a sumcient conducting nature as to insure proper processingthereof by the electric accounting machines. If the operator draws themark across the index point position in one direction only, microscopicexamination has shown that insuillcient impregnation of the fibrousmaterial of the card is attained. In other words, the microscopicprotruding fibers of the card become coated on one side only as they arecaused to lie flat against the surface of the card as the pencil ismoved thereover in one direction. If, however, the pencil stroke isreversed one or more times across the index point position of the card,both sides of the fibers become coated and a truly conductive mark isattained which offers no difflculty to the subsequent processing of thecard in the electric accounting machine. Similarly, where the mark ismade in one direction only, any sub-surface voids present in the card donot become completely filled with the conducting material and anyelevations on the surface of the card tend to become coated on only oneside thereof. These conditions are remedied when the mark is made inboth directions as described before.

The above described phenomena has given rise to the present inventionand, accordingly, it is an object thereof to provide a time recorder ofthe type shown and described in our above mentioned application inwhich, when the marking cycle of operation of the machine is reached,the marking medium is accurately brought into alignment with theselected index point position, lowered into firm and uniform contactwith the surface of the record card, and the record card is slidtransversely of the marking medium first in onedirection and then in theother to produce the desired impregnation of the fibrous materialthereof with the marking medium, whether the latter be a solid substanceor a liquid one. By such an arrangement, as briefly outlined above, itis possible to obtain a conducting mark at the selected index pointposition of the card which is of uniform size and shape and which at thesame time possesses adequate conducting properties so that there will beno electrical failure on the part of the accounting machine in which thecard is ultimately processed.

The provision of a marking apparatus of the type briefly outlined abovebeing the principal object of the invention, another object thereof isto provide a marking device designed for use in connection with this andother types of recording apparatus having novel means associatedtherewith automatically feeding the marking medium or filler incidentalto usage thereof and for compensatively absorbing any operating shocksthat may be encountered.

Other objects of the invention will be pointed out in the followingdescription and claims and illustrated in the accompanying drawings,which disclose, by way of example, the principle of the invention andthe best mode, which has been contemplated, of applying that principle.

In the drawings:

Fig. 5 is an enlarged fragmentary vertical section taken generally onthe line 6-1 of Fig. 4 and showing the interior mechanism omitted fromFig. 3, the plane of the section at the lefthand side and near thecenter thereof being spaced rearwardly from the general plane of thesection so as to show the driving connection for Fig. 8 is an enlargedfragmentary detail also showing certain elements of the carry means andas viewed from the plane represented by the line 6-6 of Fig. 7.

Fig. 9 is a plan section showing the base of the recorder and theelements of the card holder, the view being taken on the line 9-9 ofFig. 3.

Fig. 10 is a transverse vertical section through the card receivingthroat, the section being taken onthe line Ill-l9 ofFig. 9.

Fig. 11 is an enlarged face view of the feed pawl operating plate asviewed from the plane represented by the lines ll--il of Fig. 4, andshowing an example of how the presettable stops may be arranged toeffect the entering of certain desired data into the accumulator orderelements.

Fig. 12 is an enlarged detail sectional view taken on the longitudinalcenter line of a data recording pencil.

Fig. 13 is a view showing one example of a record card on which therecorder shown in Figs. 1 to 12 inclusive, records accumulated data.

Referring now in detail to th drawings and particularly to Figs. 1 to 5inclusive and 9, a preferred embodiment of time recorder is indicatedgenerally by the reference numeral Ill and comprises a supporting framestructure including a horizontal base plate ii and a pair of upstandingspaced supporting plates l2 and 13, respectively, extending across thebase H from front to rear thereof and suitably fixed at their lower endsto the base.

Mounted on the base plate II and extending from the left-hand side, asviewed in Figs. 3 and 9, to the right-hand side thereof, is a cardholder II. The card holder comprises a curved bottom plate 16 (see alsoFig. 4) and a pair of upstanding side plates l1 and 18, respectively,having their upper longitudinal edges turned over toward one another andthen downward and terminating short of the bottom plate to providespaces therebetween of the proper dimensions for receiving the upper andlower longitudinal edges of a record card IS. The card It is preferablya standard type of card used to control operation of a well knowncommercial form of electric accounting machine. In Fig. 4, the card" isis shown in its proper position in the card holder II. The card is shownin enlarged detail in Fig. 13. In order to avoid confusion, the card hasbeen omitted from Fig. 9. It is to be noted, however, that if the cardhad been shown in Fig. 9, it would have appeared therein in the sameposition as it appears in Fig. 13.

The card holder I6 is supported for limited longitudinal movement withrespect to the base plate II for a purpose which will presently ap pear.The card holder supporting means comprises a plurality of spaced rollers26 mounted, respectively, within aligned openings extending throughupstanding lugs 2| formed on the ends of bracket plates 22, the ends ofeach roller 36 extending through aligned slots 23 in the upstanding sideplates i1 and I8. The bracket plates 22 are suitably fixed to the baseplate H. The normal position of the card holder is that which is shownin the drawings. The card holder is moved only during a recordingoperation, as will later appear.

On the left-hand end of the card holder l5 as viewed in Fig. 9, is fixeda card throat 25 of suitable molded material and being formed with acurved slot 26 through which the card is may be inserted and removedendwise from the holder I6. Th throat 25 occupies a suitable recess inan end wall of an enclosing casing or cover 21 of the recorder and ismovable with the rest of the card holder. The card holder is provided atits rights-hand end with upstanding spring lingers 23 which are fixed toan end plate 23 of the card holder and extend upwardly through suitableopenings 30 provided in the curved bottom plate l6. When a card 19 isfully inserted within the holder IS, the right-hand end of the cardengages the fingers 28 and holds the latter in a deflected condition sothat at the end of a recording operation when the card is released thefingers 28 will partially eject the card l9 from the card holder.

The card is held within the card holder at all times when the recorderis operating by a card latch (see Figs. 9 and 10). The latch comprisesan arm 32 fixed at one end to a shaft 33 journaled in spaced brackets 35extending inwardly from the side plate II. The arm 32 moves within arecess 36 formed in the throat 25 and moves from a non-operatingposition where its outer,

end 31 is below the card slot 26 to an operating position shown in Fig.10 where the end 31 is across the slot 26 and engaging the left-hand endof the card I9 to hold the latter in its fully inserted position. Thecard latch is operated by a second arm 38 fixed at one end to the shaft33 and connected at its outer end to the lower end of a link 39, theupper end of the latter being pivoted to the outer end of one arm of arocker lever 40 (see also Figs. 1 and 3) which is in turn pivoted i .1 afixed stud ll projecting from the vertical support plate l2. The otherarm of the lever 4'6 is connected at its outer end to the lower end ofan operating link 42 and the latter is pivoted at its upper end to onearm 43 of a bell crank lever 45 which is fulcrumed on a fixed stud 46projecting from the plate II. The card latch lever arm 32 and theconnected levers and linkage just described are constantly urged to movein a direction to latch the card by a spring 41 connected at its lowerend to the pivot pin 8 connecting the'link 42 and lever 4'0, andconnected at its upper end to a stud 49 projecting from the plate i2.

The time recorder disclosed herein includes an operating mechanism whichoperates at a predetermined time rate. Insofar as certain of the broaderaspects of the present invention are concerned, this operating mechanismmay be of any suitable type such, for example, as a springdriven,marine-escapement clock movement, a time mechanism operated by minuteimpulses from the controlling electrical circuit of a clock system, orthe operating mechanism may comprise a synchronous or frequencycontrolled AC motor. In the-preferred embodiment disclosed herein thetime operating mechanism comprises a frequency controlled AC motor 58 ofwell known form which is suitably supported from the vertical plate 12by studs 5| and 52 and includes a motor drive shaft 53 to which is fixeda pinion 55 meshing with a gear 56 rotatably mounted on a stud 51 alsoprojecting from the plate I2. Fixed to the gear 58 is a driving cam 58.The motor shaft 53 operates at one (1) R. P. M. and the pinion 55 andgear 58 are of such relative sizes that the driving cam 58 is rotated atone-tenth R. P. H.

Coacting with the cam 58 is a cam follower 59 (Fig. l) which ispivotally supported by a stud 63 projecting from the support plate I!and is held in engagement with the cam by a tension spring 5| connectinga tail element 52 of the follower with a fixed stud 63 on the plate 12.The cam follower is formed to include a gear sector 85 which meshes witha mutilated gear 56 formed on one end of a sleeve 61, the latter beingrotatably supported within an opening provided through the support plateI! and encircling a start shaft 88 which extends through both supportplates l2 and I8 (see Fig. 5). Fixed to the sleeve 81 at the side of theplate 12 opposite to the gear 66, is a hub 59 having a pair of radialarms 10 which are connected at their outer ends to one end of asemi-cylindrical driving plate H, the other end of such plate beingconnected to the outer ends of a second pair of radial arms 12 whichterminate inwardly in a second hub 13 journaled on the start shaft 58adjacent the support plate. From the foregoing, it is apparent that withthe cam 58 rotating at the rate of R. P. H., the follower 58 isoscillated once each of an hour and the driving plate II is alsooscillated once each of an hour through its connection with thefollowers. 58, which, as just stated, includes the gears 55 and 85, thesleeve 51 and the arms ll The preferred embodiment of time recorderdisclosed herein also includes a register comprising a totalizing oraccumulating mechanism which may be operated to accumulate desirednumerical data at a predetermined time rate. The accumulating mechanismcomprises generally a plurality of accumulator order elements 15rotatably supported by the start shaft 88, a data entering means foreach of the order elements II, and an entry control means, whichincludes the driving plate H and which may be adjusted to enter anydesired digital value representation into any order element during eachoscillation of the plate H which, as stated above, occurs each of anhour while the recorder is in operation.

Bach accumulator order element is shown as comprising a ratchet wheel 16having sixty teeth a thereon. Each time a ratchet wheel 16 is advancedcounterclockwise, as viewed in Fig. 4, by the entering means, a distanceequal to one tooth space, such advance represents an entry in thatorderof one unit of digital value. The data entering means for each orderelement, or ratchet wheel, comprises an arm 11 arranged alongside itsrelated ratchet wheel and rotatably supported if at one end on'the startshaft 88. Each arm ll carries an advancing pawl 18 which operativelyengages the teeth 19 of its related ratchet wheel 18 to move the lattercounterclockwise. Each pawl 78 is pivotally connected to its related arm1! by a pin 88 extending through an opening in the pawl and through anarcuate slot 8! formed in the arm. The length of the slot 8| isequivalent toone tooth space on a ratchet wheel 16. Each pivot pin 88 isnormally held in the lower end of its slot by a tension spring 82connecting the related pawl and arm. Each pawl-carrying arm H is formedwith an integral outwardly extending projection 83 which moves within arelated slot 85 (Figs. 4, 5 and 11) formed in the semicylindricaldriving plate H.

The driving plate ll forms one element of the entry control means andthe latter also includes presettable stops 85. which are selectivelypositionable, respectively, within pairs of transversely aligned radialgrooves 81 formed in the 1 sides of the slots 85. As shown in Figs. 5and 11 there is one slot 85 for each pawl-carrying arm 11 and itsrelated order ratchet wheel 15. There are nine pairs of arcuately spacedgrooves 81 in each slot 85 and they represent, respectively, the ninedigits "1 to 9 inclusive. When a settable stop 85 occupies a selectedpair of grooves 81 in one slot 85 and the drive plate II is oscillatedby the means previously described, once each /10 of an hour, the digitalvalue corresponding to the position of such settable stop a is enteredin the related order ratchet wheel.

The plate ll moves through an arc of 63 during each oscillation. Each 6of such angular movement of the plate H corresponds to an angularmovement of one tooth space of the ratchet wheels. The remaining 3 ofangular movement of the plate TI is provided so that the pawls 18 at theupper end of their clockwise movement will override slightly the ratchetteeth and thereby assure engagement with the correct ratchet teeth. Itwill be noted from an examination of Figs. 1, 4 and 6 of the drawingsthat the follower 58 is shown at the peak of the cam 58 and the plate Hcorrespondingly is at the upper end of its clockwise movement. Each ofthe pawls is shown as being tooth space beyond a ratchet tooth. When thefollower 59 drops off'the high point of the cam 58, the plate H quicklymoves counterclockwise for the 63 under force of the spring 8| to effectentering of the digital values represented by the selected position ofthe stops 88 in the slots 85.

The digital value entry in each order is effected during suchcounterclockwise movement of the plate by the upper end 88 of itsrelated slot engaging the projection 83 of its related arm I1 and movingsuch arm 11, its pawl 18 and its ratchet wheel 15 counterclockwise anamount determined by the angular position occupied by the projection 83of such arm at the time it is engaged by the end 88 of the slot 85. Thisangular position of each such projection 83 at the beginning of itscounterclockwise movement is determined by the position of the stop 88in its related slot Ii. At the lower end of the movement of the plateII, the ends 98 of all slots engage their related projections of thepawlcarrying arms 'II. When the plate II moves upward and clockwise theprojections 93 and their pawl-carrying arms I1 will not move clockwisetherewith until such projections are engaged by stops 86 in theirrelated slots 89. Therefore, the amount of clockwise movement of eachprojection and its pawl-carrying arm and the angular.

position of each such projection at the end of such clockwise movementdepends entirely upon the position of the stop 86 in its related slot85. The digital values corresponding to the different pairs of groovesin each slot 85 are indicated in Figs. 4 and 6 by corresponding numeralsabove the grooves and in Fig. 11 by corresponding numerals along theright-hand side of the plate and opposite the grooves.

In Fig. 4 a stop 36 is shown in the 9" digit position and the plate 'IIis shown at the end of its upward or clockwise movement. Thus, when theplate II moves counterclockwise, the pawl II will move the relatedratchet wheel an amount equivalent to nine tooth spaces which representsa digit entry of nine in such ratchet wheel. The 63 angular degrees ofcounterclockwise movement of the plate II is the equivalent of 10 /2teeth oi. travel of the ratchet wheels. The first 3 of counterclockwisemovement of the plate and pawl will bring the pawl into operativeengagement with the ratchet tooth. In order to provide a digit valueentry of only nine in a ratchet wheel when the plate II moves the arm IIfor the remaining 60 of its counterclockwise movement, such as will bethe case when a stop 96 occupies the position shown in Fig. 4, therelated pawl 19 is stopped by the upper end 90 of a stop arm 9| engagingan outward projection of the pivot pin 80 when the pawl I9 has moved 54of the remaining 60 of movement of the plate II. The 54 corresponds tonine tooth spaces of movement of the ratchet wheel It. When the pin 89strikes the end III of the arm 9|, further counterclockwise movement oithe pawl 18 and ratchet wheel I9 isprevented. However, the plate 'II andarm 11 are permitted to continue their clockwise movement for theremaining 6 by reason of the slot BI in the arm I I. As will beapparent, a similar operation also takes place upon the entry of any ofthe digit values 1 to "8 inclusive; 1. e., during each.

entering operation, the plate 'II moves the projection 83 and itspawl-carrying arm 11 an angular distance equal to 6, or one tooth space,

more than the pawl 1,8 is moved, when the stop arm 9| occupies itsnormal position shown in the drawings.

The just-described extra one tooth space of movement of the plate II andarm I1 is utilized when it is desired to enter a carry unit of digitalvalue in a higher order element, which occurs when the next lower orderelement is moved from "9 to 0. When the'latter is to take place, the arm9I normally in the path of the pivot pin 90 for such higher orderelement, is moved clockwise out of the way of such pin 90 by the nextlower order element; and, as a result, the pawl I8 and ratchet wheel 19of such higher order element are moved by the arm I! the angular set atthe 5" digit position, the related pawlcarrying arm 'II would move itsratchet wheel ll the equivalent of live tooth spaces to enter five unitsin such order in the normal way and then move the ratchet wheel an extratooth space to enter the carry unit of digital value. If such nexthigher order element is being used only as a storage order element, likethe ratchet wheel I! in Fig. 6, then there would be no stop 99 set inits related slot 95 of the plate 'II and when its arm H is moved out ofthe path of its pin 29 by the next lower order element to efiect theentering of a carry, the ratchet wheel It or the higher order will onlybe advanced the one tooth space.

The carry means will be understood more clearly from an examination ofFigs. 4, 5, 6. 7 and 8. Each ratchet wheel is provided with six lugs 92circumferentially spaced so that each time a ratchet wheel representinga lower order is advanced from a position representing the digit 9" tothe position representing the digit "0," one of the lugs 92 engages andmoves a related trip lever 94 clockwise, as viewed in Fig. 6, about asupport shaft 95 extending between the two main support plates I2 andII. The left-hand end of each trip lever 94 as viewed in Figs. 4 and 6,is formed to provide a two-step positioning stop for the arm M of theratchet wheel of the next higher order. The arms 9| are pivotallysupported on a shaft 99 which is in turn supported at its ends by thesupport plates I2 and II. The arms 9| are held in either of the steppositions of its coacting trip lever 94 by a tension spring 91. Thenormal position for the arms II and coacting tri levers 94 is that shownin the drawing. When a lug 92 of a lower order trips a lever 94 andmoves it clockwise, its spring 91 moves its coacting arm 9| clockwise sothat a pin 99 carried by such arm 9| engages the lower step position ofthe lever 94 and the arm 9| then is in the position where the pin 99 ofthenext higher order element will not engage the end 99 of such arm (seethe dotted line position of the end of the arm 9| indicated in Fig. 6).The several arms II and coacting trip levers 94 are restored to theirnormal position shown during the next upward or clockwise movement ofdriving plate II, by means of depending arms 99 on the hubs 99 and 13operatively engaging, respectively, a pair of arms IIII journaled on theends of shaft 99 and connected by a bail I92 (see also Fig. 5). When thearms 99 are moved clockwise as viewed in Figs. 4 and 6 along with thedriving plate, such arms 99 move the arms IOI and hail III2counterclockwise into engagement with any of the arms 9| which weretripped to effect the entering of carry units during the entry portionof the preceding cycle of operation. The bail I92 moves the arms 9|counterclockwise to the normal position shown and thesprings 91 movetheir coacting trip levers 94 back to the position shown.

In the construction illustrated, there are fifteen order elements I!(see Fig. 5) and they are grouped to provide three separate registers oraccumulators indicated, respectively, by the reference characters I III,III! and Ill. The accumulator I05 is composed of the six order elementsat the right-hand side of Fig. 5 and is used herein to accumulate theburden or overhead cost for each Job. The legend Burden appears in Fig.

distance corresponding to the digit value to be entered in the normalway in such higher element, plus the extra one tooth space to eilect theentry of the carry unit of value. For example, if the stop for such nexthigher order element is )5 above the order elements or accumulator I95.The order element at the left of the group composing the accumulator I95accumulates tens of dollars, the second from the left accumulates 19units 0! dollars. the third tenths of dollars. 3.

fourth hundredths of dollars; the fifth thousandths of dollars, and thesixth ten-thousandths of dollars. The accumulator I88 is composed of thesix order element I to the left of the accumulator I85, and is used toaccumulate the labor cost for the job. The legend "Labor" appears inPig. 5 above the order elements of this adcumulator. Like theaccumulator I85, the order element II at the left of the group composingthe accumulator I88 accumulates tens of dollars. the next one to theright thereof accumulates units of dollars, the next tenths, the nexthundredths, the next thousandths, and the sixth from the leftaccumulates ten-thousandths. The accumulator III is composed of thethree order elements at the extreme left of Fig. 5 and is used toaccumulate the time required for each Job. The legend "Hours" appearsabove this accumulator Ill.

The order element 18 at the right of the group composing accumulator I"is used to accumulate tenths of hours. the next order to the leftthereof stores units of hours, and the one on the extreme left storestens of hours. The order elements at the extreme left of the accumulatorI85 as viewed in Fig. 5, and the order element at the extreme left ofaccumulator I88 are not provided with trip levers 88, the reason beingto prevent carrying operations between accumulators.

One example of the manner in which the recorder may be used toaccumulate digital values, is indicated in Fig. llby the positions ofthe stops 88 in the pairs of grooves 81 in the slots 85. As Fig. 11shows the outer face of the driving plate II, which is the one oppositeto that shown in Fig. 5, the positions of the slots 85, Fig. 11,corresponding, respectively, to the order elements I! of theaccumulators I05, I88 and I81, are reversed with respect to theirpositions shown in Fig. 5. The three slots 85 at the right of Fig. 11are those corresponding to the accumulator I81 which stores units oftime. The legend "Hours" appears at the top of these three slots. A stop88 is shown in the 1" digit position of the left-hand one of the slots85 and no stops 88 are shown in the other two slots. With thisarrangement one digital unit of time is entered into the correspondingtenths order of the accumulator I81 each of an hour. As no stops 88 arein the other two slots 85 of the accumulator I81, the order elementscorresponding thereto merely store digital units of time which areentered therein by the carry means as explained above. The six slots 85at the left of those just described are those corresponding to the orderelements of the accumulator I88. The legend Labor appears over the topof these six slots. The example selected for a labor rate is ninety-oneand one-half cents an hour. Hence, the stops 88 are set in the properslots to eifect the entering during each of an hour in the orderelements of the accumulator I88 digital values representing nine hundredfifteen ten-thousandths of a dollar ($0.0915). The legend Burden appearsover the top of the six slots 85 at the left of Fig. 11 as these slotscorrespond, respectively, to the six order elements of the accumulatorI85. The selected example of a burden rate is one dollar and fifty-eightand one-half cents ($1.585) p hour. Consequently, stops 88 are so placedin the slots 85 under the word Burden in Fig. 11 that each of an hourthe plate II provides for the entering in the related order elements ofaccumulator I85 of digital values representing fifteen hundred andeighty-five ten-thousandths of a dollar (80.1585) It will be obviousthat the 10 order elements of both accumulators I85 and Illcorresponding to the slots 85 shown in Fig. ll

with no stops 88 set therein, will function purely as storage orders.

From the foregoing, it will be apparent that,

with the motor 88 operating, during eachonetenth of an hour one unit ofdigital value will be entered into accumulator I01, digital valuesrepresenting 80.0915 will be entered into the accumulator I88, anddigital values representing 80.1585 in the accumulator I85. The drawingsshow the order elements in the positions they occupy after one enteringoperation has taken place and show the cam 88, the plate II and thepawl-carrying arms I! in the position they occupy just, before thebeginning of a second entering operation.

The recorder disclosed herein also comprises a mechanism which isoperated by the workman when a particular job is finished, to record inone operation on the record card I9 in the card holder I5, the amount oftime spent on the Job which is standing in the accumulator I81, themoney value of the labor at the workmans rate which is accumulated inthe accumulator I88,

V and the money value of the burden or overhead cost at thepredetermined rate which is standing in the accumulator I05. To thisend, each order element I5 of the three accumulators also comprises astar wheel H0 fixed to the side of its related ratchet wheel I6 andincluding six identical segments I I I, with each segment being formedat one side with ten positioning steps II2 corresponding, repectively,to the ten digits "0 through "9," and being formed on the opposite sideas a radially extending straight edge H3. The lowest step I I2a of eachsegment corresponds to the digit 0 and the highest step I no the digit9.

As shown in Figs. 3 and 4, the recording mechanism comprises a pluralityof levers II5 corresponding, respectively, to orders of theaccumulators, and pivoted at their upper ends on a. shaft I I8 supportedby the two plates I2 and I8 so that when a recording is to be effectedthe levers II5 may be moved in planes normal to the axis of the starwheels II8. Each lever II5 comprises a downwardly extending arm Ill anda laterally extending arm I I8 and is held in its normal position shownby a bail rod 9 engaging the arms II8 of all of the levers. The bail rodH9 is connected at its ends to spaced lever arms I28 fixed to a stopshaft I2-I which extends through both supporting plates I2 and I3. Eachlever H5 is constantly urged to move in a clockwise direction about itssupporting shaft I I6 by a tension spring I22 connected at its upper endto a tail element I28 of such lever H5 and connected at its lower end toa rod I 24 removably held at its ends in slots I25 in brackets I28carried by the support plates I2 and I3 (see Figs. 1, 2, 3 and 4). Thearm II I of each lever II5 carries at its lower end a pencil barrel I28(see Figs. 4 and 12) for slidably holding and guiding a lead I29 whichis made of a suitable electrically conducting mate- 11 order of theaccumulator of which the step I I2 is a part.

With the exception of the denominational orders representing thousandthsand ten-thousandths of dollars in the accumulators I05 and I05, a leverI I 5, with its arm I I1 carrying a pencil barrel I23; is provided foreach denominational order of each of the three accumulators shown (seeFig. 3). The reason for omitting levers II5 from the orders just namedis that there would be no practical value in recording on the card thefractional values standing in such orders, such orders being useful inentering labor and burden rates requiring the use of fractional values,like the example of rates given hereinabove.

In Fig. 13 of the drawings there is shown an example of record card I9designed for use with the recorder disclosed herein. The card I9 is aconventional 80 column card used with electrical accounting machines,which has been specially designed for use with the recorder of thepresent invention. The smaller numerals indicate the index point ordigit positions of the columns which may be punched to represent data ina manner well known in the accounting machine art. The larger numeralsindicate index points or digit positions used for recording by thepresent recorder. It is noted that the positions used by the presentrecorder are staggered with respect to the accounting machine positions.This is so that data may be recorded by punching in the usual way in allof the 80 columns. The card I9 is provided with three fields of thelarger numerals for recording by the present recorder, such fields beingindicated by the numerals I32, I33, and I34 and corresponding,respectively, to the accumulators I35, I03 and I01. As shown, the fieldI34 is composed of three columns of ten digit positions for the purposeof recording on the card the time consumed on the job which is standingin the accumulator I01. The field I33 is provided with four columns often digit positions for recording the money values of the labor on thejob standing in accumulator I03. The

field I 32 is provided with four columns for recording the money valueof the burden or overhead standing in accumulator I05.

. When the card I9 is fully inserted within the card holder I5, thelower ends of the barrels I23 which are carried by the several arms II!are aligned, respectively, with the columns on the card which correspondthereo and which correspond to their related OIdGl. elements 1-5 of theaccumulators I05, I03 and I01. The proper alignment is maintained by aguide plate I35 suitably fixed to the upright support plates I2 and I3and formed with guide slots I36 receiving, respectively, the lower endsof the barrels I23 (see Figs. 3 and 9).

Associated with each lever H5 and its arm H1 is a second arm I31 whichpositions and operates the pencil lead I29 in the barrel I28 of itsrelated arm II 1. The upper end of each arm I31 is formed with a slotI38 (see Fig. 4) receiving the shaft H3, and with an upper cam surfaceI39 adapted to be engaged by a cam operated bail I40 when a recording isto be effected, as will presently appear. As shown in Fig. 12, the lowerend of each arm I31 is pivoted by a pin I to one end of a rocker leverI42, the latter being pivoted intermediate its ends by a pin I43 on itsrelated arm III and the other end of each rocker I42 being connected bya tension spring I44 to a projection I45 of its related arm II1. Eachspring I44 functions through I 12. its rocker lever I42 to ing thebottom of its slot I33.

vertically movable within the bore of its barrel I23'and is connected bya spring I41 to the lower end of a rack I43 which also moves axiallywithin the barrel. Each rack I43 is held firmly by two pawls I 49 andI50 extending through slots I5I and I52 in the barrel I23 and engagingteeth I53 and I54, respectively, formed on upposite sides of the rackI43. The upper ends of the pawls I 49 and I50 are pivoted, respectively,by'the pin I and by a pin I55 to the rocker lever I 42. A tension springI53 connecting tail elements I51 and I 53 of the pawls I43 and I50,respectively, constantly urges the pawls into engaging relationship withtheir respective sets oi. teeth. The pivot pins HI and I55,respectively,

'are spaced such distances from the pivot pin moves a distance equal tothree of the rack teeth I54. As will be noted. the teeth I54 and pawlI50-are so shaped that the rack I43 can move downward with respect tothe pawl I50 and that the pawl I50 can move upward with respect to therack, the pawl I50 simply ratcheting over a tooth I54 into the nexttooth space. However, the shape of the teeth I54 prevents upwardmovement of the rack with respect to the pawl I50 for a distance as muchas one tooth space. The teeth I53 and pawl I49 are so shaped that theycan be moved any number of tooth spaces relatively to one another ineither direction. When suflicient force is applied to effect the latter,the pawl I49 will be cammed by the teeth I 53 out of one tooth into thenext.

I When the arms I31 are moved downward by the cam operated bail I40 forthe purpose of efiecting a recording, in a manner which will bepresently described, each pair of cooperating pawls I49 and I50 movetheir related rack I43 downward in the barrel I23. With a fresh lead I29in a barrel I23, the lower end of the lead I29 will touch the recordcard I9 when the rack I43 has been moved downward from the positionshown a distance equal to one tooth space. When the rack has moveddownward a second tooth space the minimum amount of compression pressurewill be placed on the spring I41 to effect marking on the card. Furtherdownward movement for the next or third tooth space will placeadditional compression pressure on the spring I41 without damaging thelead. The relative strength of the springs I41 and I53 is such that witha fresh lead further downward movement of the rack I43 beyond the threetooth spaces just mentioned, will be prevented by the resistanceofiered-by the spring I41, and the spring I55 will then yield andthereby permit the pawl I49 to be cammed out of one tooth space into thenext. This action will permit the pawl I49 to be moved downward relativeto the rack I43 a distance equal to the two additional tooth spaces ofthe full travel of pawl I 49. At the end of downward travel, the pawlI50 will fully occupy a tooth space, the length of its travel beingthree tooth spaces while the pawl-I49 travels five. When the arm I31 ismoved upward and back to its normal position shown the rack I48 israised due to the gripping force of the pawls I49 and I 50. Because thepawl I49 moves five spaces while the hold its arm m in its' normal restposition with the shaft II3 engag- 13 pawl Ill moves three and as theshape of the teeth I" prevent upward movement of the rack I with respectto the pawl I50 for a distance as much as one tooth space, the rack ismoved upward three spaces and the pawl I49 will cam over the other twotooth spaces of its travel. As succeeding recordings are eflected thelead I2! will wear away; and, as the latter happens, the pawl I4! movesthe rack I48 downward increasing distances before the resistance offeredby spring I41 overcomes the force of the spring I" and the'pawl I49 camsover its teeth I53 to permit its full downward travel of five teeth.When enough lead is worn away so that the pawl I4! is permitted to movethe rack the equivalent of four tooth spaces before it is cammed out ofthe tooth space it is occupying, the pawl I58 will then cam over a toothI54 into the next higher tooth space. Then, as

the pawl I" will only permit the rack I48 to move upward a distance ofthree tooth spaces on the next upward movement of the arm I31, the rackI 48 and lead I29 will occupy a lower position with respect to the pawlsand the lead will then have been fed downward a distance of one tooth.This feeding action will. of course, continue with succeeding recordingsuntil the lead is used up and needs replacing.

Before a recorder is assigned to a workman, an authorized person, forexample his supervisor, having a master key, not shown, unlocks the lockI and removes the cover 21 and sets the stops ll in the proper grooves81 of the slots '5, so that for each one-tenth of an hour while therecorder is in operation, one unit of digital value will be entered inthe elapsed time accumulator I", digital values representin the workmanspay rate for one-tenth of an hour will be entered in the laboraccumulator IIIG, and digital values representing the burden rate forone-tenth of an hour will be entered in the burden accumulator I05.After setting the stops 88 in the desired position, the cover 21 isreplaced and locked and the recorder given to the workman.

When a workman begins an assigned job he effects a "start operation" ofthe recorder I 0, during which a fresh record card I9 is inserted in thecard holder I and locked in position by the card latch lever 32. Thestart operation is effected by inserting a key IGI (Fig. 3) in a keyhole I62 in the end of start shaft 68 and turning the key I6I first 60clockwise as viewed in Fig. 2 and then turning the key 60counterclockwise back to the position shown. The card I! is fullyinserted in the card holder when the key has been turned the 60clockwise and, as will later appear, is locked in position when the keyis turned counterclockwise back to the position shown. The parts areshown in full lines in Fig. 2 in the position they occupy after a startoperation has been completed. Before a start operation, a start-stopinterlock element I64, which is pivoted on a stud I65 carried by thesupport plate I3, is in the dotted line position thereof shown in Fig.2. When a start operation is begun by turning the shaft I clockwise 60as above noted, the outer corner of an edge I65 of a segmental plate I61fixed on the shaft 68, engages the lower end of a finger I68 of thepivoted interlock I84, with the latter in the dotted line position, androtates the interlock in a counterclockwise direction about the pivotstud I65. When the interlock has been rotated counterclockwise farenough where an over-center tension spring Ill, connecting a tailelement III of the startstop interlock I64 and a fixed stud IlIa on thesupport plate I3, moves below the axis of pivot stud I", the spring I"will then urge the interlock I64 in a counterclockwise direction andwill thereby quickly move the lower end of finger I12 into engagementwith the periphery of plate I". When theworkman rotates the shaft 68counterclockwise back .to the position shown, the lower notched end offinger I'I2 engages behind the outer corner ofedge I66 as shown in fulllines in Fig. 2, and thereby locks the shaft 61 in the position shown.The shaft 68 can be unlocked and another start operation effected onlyafter the workman has effected a stop operation in a manner which willappear more fully hereinafter.

When the above described 60 clockwise rotation or the shaft 6! begins, aspring-controlled detent I13 is engaged by the outer periphery of asecond segmental plate I14 fixed to the shaft 68, so that a reverserotation of the shaft 68 is prevented by the detent until a corner I15of the plate I14 passes the outer end of the detent and thereby providessuillcient clearance for the detent so that its spring can return it tothe position shown in Fig. 2. The latter will happen at the end of the60 of clockwise movement. The 60 clockwise movement of the shaft 68 islimited by a stud US on the plate I I engaging the edge I" of the plateI14. The detent I13 is also engaged by the periphery of plate I" whenthe return 60 counterclockwise movement of shaft 68 is begun and thedetent thus prevents a reverse direction of movement of the shaft 68until the 60 of counterclockwise movement is approximately completed. Astud I'I'I shown in Fig. 2 as engaging the edge I18 of plate I14,determines the normal position of the shaft 68.

As shown in Fig. 1, the other or left-hand end of start shaft 68 isprovided with a segmental cam plate I80 fixed thereto and having arelatively high step surface IBI of greater radius and a low stepsurface I82 of lesser radius. A second arm I83 of the bell crank lever45, previously described, is formed at its outer end as a cam followerand is normally held in engagement with the periphery of the cam plateI80 by the spring 41. The bell crank 45 is also formed with a third armI84 which extends upwardly and is provided at its upper end with a pivotpin I85 on which a spring pressed dog I86 is pivoted. The latter isprovided with a hook portion I81 normally held in engagement with theright-hand side of the arm I84 as viewed in Fig. 1, by a tension springI88 connecting a tail element I89 of the dog I88 and'a stud I90 0n thearm I84. The function of the dog I86 will be explained laterin-connection with the de-, scription of the stop operation.

A second three-arm bell crank or lever I92 is fulcrumed on the stud 46and comprises one arm I93 which operates a switch I94 connected inseries with the synchronous driving motor 50; a second arm I95 whichcoacts with a spring controlled latching dog I56 pivoted on a stud I91extending from the plate I2; and a third arm I98 having a pin I99 in theupper end thereof engaging the peripheral surface of a cam disc 200fixed to astop shaft I2I.

As stated hereinabove, the parts are shown in the relative positionsoccupied when the recorder is operating. As will be explainedhereinafter,

when a stop operation is effected the lever I92 is rocked clockwise asshown in Fig. 1, to a position where the outer pointed end of arm I95thereof is latched and held latched by a projection I on the latchingdog I96. in moving to the latter position, an insulated projection 202on lever arm I93 moves the upper end of a switch actuating member 203 tothe left. This will permit the inherent spring force in aspring switchblade 204 to move such blade also to the left and thereby open contactpoints 205 to stop the motor 50. The member 203 is in the form of a flatspring plate having a greater spring force than the switch blade 204 andso mounted at its lower end that it constantly urges the switch blade ina switch closing direction, which is to the right as viewed in Fig. 1.The just described latched position of lever I92 is the one occupiedthereby when the recorder is not operating and before a start operationis effected.

With the lever I92 latched in the manner just explained, the initialrotation of the start shaft 50 by the key I6I in a clockwise direction,as viewed in Fig. 2, will move the cam plate I" counterclockwise 60 asviewed in Fig. 1, with the result that the rocker arm 45 will be rockedclockwise to move, through the linkage previously described, the arin32of the card latch downward as viewed in Fig. 10 and thereby clear thecard slot 25. A card I9 like the one shown in Fig.

13 is then fully inserted within the slot 26 and the card holder I5 andheld therein by hand while the key I6I is turned counterclockwise asviewed in'Fig. 2 back to the position shown. This will result in the camplate I80 being rotated clockwise, as viewed in Fig. l, to the positionshown, and in returning the rocker lever 45 and card latch arm 32 to theposition shown in Figs. 1 and 10, where the arm 32 is across the slotand holding the card I9 in its fully inserted position.

When the cam plate I80 is rotated 60 counterclockwise, as viewed in Fig.1, during the first half of a start operation, a lug 2I0 fixed on theside of the cam plate I80 engages the lower end of latching dog I96 andmoves the latter clockwise out of latching position. The springmember'203 pressing on the lower end of arm I93 then moves the levercounterclockwise, but not far enough to close the switch points, becausea lug 2 on arm I93 engages and is thereby stopped by the underside ofarm 43 of lever 45 which at this time is held by'the high step I8I ofthe cam plate I80. When the shaft 68 and cam plate I80 are rotatedclockwise, as viewed in Fig. 1, and back to the position shown to finishthe start operation, the lever I92 will then move counterclockwise alongwith the lever 45 and the switch points will be closed to start themotor 50.

During the first half of a start operation when the shaft I58 is turnedfor the 60 counterclockwise movement as viewed in Fig. 4, each of theorder elements I5 having a digital value standing therein due to aprevious entering operation is reset by being turned counterclockwise tothe next 0 digit representing position. The latter is effected by aplurality of radially extending arms 2 fixed at their inner ends to theshaft 98 and extending between adjacent order elements. There is one arm2I4 provided for each order element I5 and it extends outwardly alongthe side of the order ratchet wheel I6 from which the lugs 92 project.The arms 2I4 are made of a spring metal and engage at theirouter endsthe 16 side surface of their related order ratchet wheels I6. The lugs92 are wedge shaped, as shown, so that during entering operations thelow side of the lugs 92 engage under the outer ends of the spring armsand the latter are forced outward so that the arms 2I4 can be passedwithout interference. When the start shaft 58 is turned for the 60counterclockwise movement as viewed in Fig. 4, to begin the startoperation, all of the arms 2 move counterclockwise therewith and willengage the high sides of lugs 92 of any of the order ratchet wheels I0which are positioned to represent digital values from 1 to 9" inelusiveand will rotate such ratchet wheels counterclockwise to a position wherethey will represent the digit 0. For example, the ratchet wheel I6 inFig. 4 is positioned to represent the digit "9. Thus, should the shaft83 be rotated 60 counterclockwise the arm 2 shown will engage the highside of lug 92a and will move the ratchet wheel I6 one tooth spacecounterclockwise so that the cam finger I30 shown will be opposite thelowest step I I2a of the next segment. III which lowest step representsthe digit '0," as stated previously.

With all order elements turned to "0, and a fresh card I9 fully insertedand locked in the card holder and with the switch contacts 295 closed,the recorder then begins to operate and will continue to operate andaccumulate values in the manner above explained until the workmaneffects a stop operation. He will do this when the assigned job iscompleted and when work on the job is stopped for any length of timesuch, for example, as during lunch hour or at the end of the workingday. When a stop op-- eration is effected the switch contacts 205 areopened to stop the motor and the digital values standing in theaccumulators are recorded in corresponding columns of the card I9. Asstated hereinabove, the parts are shown in the position they occupyafter the recorder has gone through one entering operation. By way ofexample, the stop operation will be described as taking place with theparts in the position shown.

. A workman effects a stop operation of the recorder by inserting thekey I6I in a key hole 2I5 provided in the right-hand end of stopshaft-I2I (see Fig. 2) and by turning the key and shaft first 180counterclockwise until the edge 2I9 of a segmental plate 2I'I fixed tothe shaft I2I engages a stud 2I8 projecting from the support plate I3and then by turning the stop shaft- I2I 180 clockwise until the edge 2I9of the plate 2! engages the stop 2I8, as shown in Fig. 2. The stop shaftI2I is also provided with a segmental plate 220 fixed thereto, and whenthe shaft- I2I is turned for 180 counterclockwise movement as viewed inFig. 2 during the first part of the-stopoperation an edge 22I of theplate 220 engages the outer end of a finger 222 extending from the startstop interlock element I64 and moves such finger 222 and interlock I64clockwise to a point where the over-center spring I10 .is above the axisof the pivot pin I65. When the latter happens, the spring I'I0 willcontinue the clockwise movement of the interlock I64 until the uppernotched end of finger 223 engages the periphery of member 220. When thestop shaft I2! is then turned for clockwise movement to complete thestop operation and to the position shown in Fig. 2, the upper notchedend of finger 223 will engage the outer corner of edge 22I of member 220and thereby lock the shaft I2I in the stop 76' Position. The latterposition of the interlock I54 is indicated in dotted lines in Fig. 2, aswas explained previously. As was the case with the start shaft, a springcontrolled detent 225 coacts with the peripheral surfaces of thesegmental plate 2" to assure that when either a clockwise or acounterclockwise movement of the stop shaft is commenced such movementmust be completed before movement in the opposite direction can beeflected.

Referring to Fig. 1, it will be apparent that the cam disc 200 on theleft-hand end of the stop shaft I2I will be moved first 180 clockwiseand then 180 counterclockwise, when a stop operation is efiected.Movement of the cam disc 200 for 180 clockwise movement will cause thepin I89 on the upper end of arm I98 to move out of a recess 221 in thecam 200 and onto the high surface of such cam and thereby provide for aclockwise movement of the lever I92 from the position shown. The latterwill result in the arm I95 engaging the latching dog I98 to latch thelever I82 at the end of such clockwise movement, as previouslyexplained. Also, the arm I93 will move the switch actuating member 203to the left and thereby effect the opening of the switch contacts 205and stop operation of the motor 50. It is noted that the latching of thelever I92 and the opening of contacts 205 are effected at the verybeginning of each stop operation.

It is also noted that as the cam plate 200 rotates 180 clockwise tobegin the stop operation, a pin 228 projecting therefrom engages theupper surface of the dog I85 and moves the latter counterclockwise aboutits pivot pin I85 against the force of the spring I88 until the pin 228clears the dog. The spring I88 then returns the dog to the positionshown in Fig. 1, As the cam plate 200 is rotated 180 counterclockwise,as viewed in Fig. 1, back to the position shown to complete the stopoperation, the pin 228 engages the inclined edge 228 of the dog I88 nearthe end of such movement and through the hooked end II! of the dogengaging the right side of the lever arm I84, moves the rocker lever 85clockwise to effect operation of the card latch arm 82 to release thecard l8 within the card holder I5. As will be apparent from the previous description, when the rocker 85 is moved clockwise the card latcharm 32 shown in Fig. 10 will be moved clockwise or downward to clear thecard throat and the spring fingers 28 at the right-hand end of the cardholder as viewed in Fig. 9 will then partially eject the card I8 fromthe holder so that the card can be withdrawn the rest of the way byhand. Thus, the card I9 is released at the completion of the stopoperation.

when the stop shaft I2I is first rotated 180 counterclockwise, as viewedin Fig. 2, the shaft I2 I will appear in Fig. 4 as being rotated 180clockwise and, as this happens, the bail I I8 carried by the arms Iwhich are fixed to the shaft I2I, will also move clockwise and therebypermit the arms 8 of all of the recording levers I I5 to rotateclockwise under force of the springs I22 until the fingers I on sucharms II8 engage positioning steps 2 of their related order elements 15.by the related steps II 2 and the pencil barrels I28 carried therebywill be properly positioned.

above the digit positions on the record card corresponding to the digitvalues represented by the positions of the related steps II2.

Near the end of the clockwise movement of the shaft I2I, as viewed inFig. 4, cams 282 fixed The levers II5 are thus positioned to the ends ofshaft I2I (see also Fig. 5) engage arms 233 which are pivoted on studs234 extending from the inside of the support plates I2 and I3,respectively. The arms 233 carry the bail I 5 previously referred to asengaging with the upper ends-of all of the pencil operating arms I31.Thus, when the cams 232 engage the arms 233 they move the latter and thebail I40 clockwise, as viewed in Fig. 4, and thereby effect a downwardmovement of all arms I31 to provide operative engagement of the pencilleads I29 with the card I9 in the manner previously described.

As shown in Figs. 2 and 3, the right-hand end of the stop shaft I2I isprovided with a cam 235 which engages the upper end of a lever 238fulcrumed intermediate its ends on the start shaft 88. The lower end oflever 236 engages the outer end of an arm 23! of a bell cram 238 pivotedon a stud 239 extending upwardly from the base plate II (see Figs. 2, 4,and 9). The other arm 240 of the bell crank 238 engages a pin 24Iextending downwardly from the bottom plate I6 of the card holder I5. Atension spring 242 connected at one end to the pin 2 and at its otherend to the upright support plate I3 maintains the pin 2 in engagementwith the arm 240 of the bell crank 238 and thereby also keeps arm 23!-in engagement with the lower end of lover 236 and keeps the upper end ofthe lever 235 in engagement with the cam 235 on the stop shaft I2I.

As will be seen from Fig. 2, when the stop shaft I2I is turned 180counterclockwise to effect the first part of the stop operation, thehigh point of the cam 235 engages the upper end of the lever 236 nearthe end of its movement and thereby moves the latter clockwise about itsfulcrum to move the bell crank 238 and the pin 2 against the force ofthe spring 282. As 40 the pin 2 is fixed to the card holder I5, suchmovement will result in the card holder being moved to the left, asviewed in Fig. 9. When the stop shaft I2I is then rotated 180 clockwise,as viewed in Fig. 2, to complete the stop operation, the upper end ofthe lever 235 will move from the high point of the cam 235 during thefirst part of this movement and back to the position shown, which willresult in the spring 242 returning the card holder I5 to the positionshown in Fig. 9. The just described movement of the card holder I5 tothe left. as viewed in Fig. 9, during the latter part of thecounterclockwise movement, as viewed in Fig. 2, of shaft I2I, and thereturn movement of the card holder to the position shown during thefirst part of the clockwise movement of shaft I2I, occurs at a time whenthe leads I29 are held in engagement with the card I9 by the bail I40and arms I31, as previously described. It is obvious that such movemenisof the card holder will result in the placement of elongated andsubstantially rectilinear areas of the electrically-conducting materialon the surface of the card in the vicinity of the selected columnarindex point positions thereof as 05 shown in Fig. 13. These elongatedmarks extend a slight distance to each side of the center of the cardcolumns and the long axes of the marks are transverse to the columnaraxes. In actual practice it has been found that by moving the carriagefirst in one direction and then in the opposite direction so that themarking device retraces its original marked path, a mark possessingsuperior electrical conducting qualities is attained and there is littlelikelihood of failure of the sensing apparatus in the accounting machineabscess during subsequent processing of the cards. Whereas in the priorart where marking of the cards is in one direction only, certainmicroscopic voids in the surface of the card fail to receive thereon acoating of the marking material, in the present instance, where markingtakes place in opposite directions, these voids are completely filled.Furthermore, when marking in one direction, the surface fibers of thecard become coated on one side thereof so that after the card has beenremoved from the machine and the fibers become erect only partialconductivity is afforded. when the marking device is caused to retraceits path of travel relative to the card, the fibers are brushed aside,so to speak, in opposite directions and the conducting marking materialis applied to both sides of these fibers, thereby resulting in a coatedarea of relatively low ohmage and consequent high conductivity.

As stated, the stop operation is described herein as taking place afterone entering operation has been effected. Consequently, electricallyconducting marks are placed on the card I! in the index point positionsof the columns to represent the amounts standing in the threeaccumulators after one entering operation, Fig. 13 shows the card withthe amounts recorded thereon. The electrically conducting marks areindicated by the reference character 245.

Record cards having numerical data recorded therein by the time recorderof the present invention and in the manner described hereinabove, may beused in apparatus of the typ disclosed in U. S. Patent to Bryce No.2,007,391 and Johnson No. 2,275,396, wherein they will control thepunching of numerical code hole designations in the index pointpositions of standard electrical accounting machine cards.

While there have been shown and described and pointed out thefundamental novel features of the invention as applied to a preferredembodiment, it will be understood that various omissions andsubstitutions and changes in the form and details of the apparatusillustrated and in its operation may be made by those skilled in theart, without departing from the spirit of the invention.
